To all whom it' may concern.-

Be it known that I, BERNARD STAUB, a citizen of the Austrian Em ire, and resident of the borough of .Brookfyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Im rovements in Fire and Burglar Alarms, 0 which the following is a specification.

S stems of signaling have heretofore been use in protecting houses against fire and burglary and in nearly all cases they consist of e ectrical devices in connection with thermostatic control in the case of fire alarms, or of extensive wire systems in case of burglar alarms. In systems of this general character, a central station is required, which, as a rule, comprises a visual si al apparatus, an

e vices for the central apparatus, controlled from distant sta tions.

The object of the present invention is to reduce the electric equipment of the system to its utmost limitation for the reason, that its installation is too expensive and easily disturbed and brought out of order.

The invention, in carrying out this object, consists of a central apparatus of a simple and entirely mechanical structure, operating an electrical contact, which in being closed, causes a source of electric energy to operate an electric bell, while another part of the central apparatus operates a visual signal device, so that the eye as well as the ear is informed, should any disturbance of the character specified, have taken place at-any part of the system, distant from the central station.

The system further comprises a net of combustible threads, one for each room or set of rooms of the building to be protected and extending to tlia cerrtral'station, these threads are normally held in a tightened condition by a spring controlled rotatable disk at the centra station. shafts having the same axis and are provided witha visual annunciator drop, indicating the number of a room or the thread leading to the same and connected to the res ective disk. The springs, controlling the disks, are held under tension by the ti htened threads, and in case a thread is burned or cut, the corresponding disk at the central station by its partial rotation indicates where the dlsturbance took place, and causes the o era tion of an electrical or otheralarm 0100 r, as heretofore stated.

The disks are arranged on pulling or stretching the thread and getting it out of place, as in case of protective thread netting inburglar alarms.

In the accompanying drawings, Figurel is a diagrammatic illustration of the entire system; Fig. 2 is a front view of the central apparatus; Fig. 3 and Fig. 4 are side elevatlons of the device; Fig. 5 is a vertical section in the line AA of Fig. 2; and Figs. 6

and 7 are details of construction of the cutting devices, located at distant stations.

The central station apparatus, illustrated in Figs. 2-5, comprises a base plate 1, su ported upon legs 2, which latter are proper y secured to a wall or the partition of a room, so that the a paratus is easy of access, or in lace where t e attention of passers by may fie called to the apparatus by the ringing of the bell or gong of the same. A number of bearing lugs 3 carry a corresponding number of rotatable disks 4', each of which is provided with a display part 5, showing preferably a zero mark and a mark identifying the room to which the disk by its controlling thread is connected. Each disk is held against rotation in one of its directions, by a spiral spring 6, one end of which is secured to the periphery of the disk, while the other end of the same is fastened to the base plate 1. Each disk shows two stops 7 and 8, for limiting its rotation within a certain degree.

A cord or string 9, of combustible material, is secured to the disk 10, and is capable of holding the s ring 6 under tension. The threads 9 are le to different rooms, intended to be rotected by the system, over a number of rol ers, such'as 11 of the central apparatus, and 12 and 13 at the distant rooms. Each of the threads is furthermore secured at the distant rooms 'in its tightened condition to a peg or other suitable device 14. A shaft 15, arranged parallel to the axis of the disks, carries a number of rigidly connected levers 16, one for each disk and capable of being actuated by a pin 17, at or near the fastening point to the disk 4 of the spiral spring 6. One

,4 5 string 26, instead of releasing the pull 5 of contacts 21 and 22 are connected through a suitable source of electric energy to a gong or bell, as well known in the. art. The terminals 21 and 22 consist of a contact brush 23 on one terminal and the anvil 24 on the to second terminal, capable of being brought in contact by means of the lever 18. The entire central station is inclosed in a box 25,

having a series of windows 26, through which the display part of the disks maybe in- As stated hereinbefore, the cords or strings '9 of combustible material, hold the disks 4 in such a position, that thesprings 6 areunder tension, and the zero dis lay may be seen through the windows of t e box. In order to place a number of rooms or a number of threads or strings of the same room in connection with thecorresponding disk at the central station, a main thread or cord may be 2 5 led from the disk over suitable rollers to the rooms and fastened to a plug or other means, while a cutting device (Fig. 6).is located in such a manner and lace that should it become released, it w1l cut the main thread 0 and, thereby, cause the operation of the central apparatus. This release is brought about in a way similar to the actuation of the central apparatus, by means of threads 26, secured to a bell-crank 27, one arm of which 5 is provided with a cutting edge 28, capable of cutting the thread 9, passin through a suitable hole in a sup ort 29 o the cutter. The cutter is controlled by a blade spring 30. One end of the thread 26 is secured to a suittension.

Fig. 7 illustrates a cutting device, which, in contra distinction to the device illustrated in Fig. 6, is operated-by pulling the For this purpose the bell crank 31, to which the string 26 is secured, is provided with a notch 32, normally holding a in 33 ,of the cutting lever 34. The bell cran 31 is held under the 40 able plug, so as to hold the spring 30 under tension of the spiral spring 35, while the cutting lever 34 under that of the blade spring 36. It is obvious that by pulling the string 26, the lever will release the pin 33, and the knife edge, under the action of the spring 36,

cuts the thread 9 ina similar way as the ap- When one of paratus illustrated in'Fig. 6.
